Digital Control Operation
Timed Skimming Default
Through the “User Interface” three
levels of skimming may be selected in
the “default” mode. By selecting one of
the skimming buttons – I, II, or III - the
skimming cycle (see table below) is
activated. The LED associated with
the selected button is illuminated
continuously as an indicator of the
selected skim cycle and as a “power
on” indicator. If the skimming level is
changed during an active skimming
cycle, the next active skim cycle will be
at the new setting (The LED associated
with the newly selected level will change
immediately). If the skimming cycle
is changed between active skimming
cycles the next skim cycle will be at the
new level.
Motor Exercising
For all default mode skimming levels, the
motor will be energized for 30 seconds
every 9.5 hours. Only the motor will be
energized (no heater operation) at these
exercising times.

Light Setting:

Start Button Operation
Any time the start button is depressed the “time between skims” the digital control goes to its maximum time and
operation begins for the selected skim level. After this skimming cycle the normal time delay to the next skim cycle
is used (skim cycle resets when the start button is depressed).
Heater Operation
The heater operates under Thermistor control any time the skimmer motor is energized and anytime the liquid
temperature drops to 40º F to prevent liquid from freezing. Contact Thermaco for programming alternative heater
settings.
